Using _base as a timebase hint to the muxer Stream #0:1(eng): Audio: mp3 (mp4a / 0圆134706D), 48000 Hz, stereo, s16p, 12 Hi hlcfan, you’re right, the first step would be to demux the MP4, but you’re using .Demuxer, that is able to demux MPEG-TS stream, not MP4.We don’t have MP4 demuxer in Membrane yet, though it’s in the roadmap. a basic demultiplexer called 'bmp4demux' capable of reading and dispatching.

They are not full applications, just examples taking some MP4 files as input and displaying some information about the media samples contained in the file.

The program continued executing, the audio was fine but the. We have added to GPAC some sample applications demonstrating how to use GPAC to demux MP4 files. Set AVStream.time_base instead" after the call avformat_write_header(ofmt_ctx_v, NULL) and another one after the call to avformat_write_header(ofmt_ctx_a, NULL).

When I tracked my output when using the avcodec-57.dll version of FFMPEG (most recent version), there was actually an error "Using _base as a timebase hint to the muxer is deprecated.

When I reverted to an older version of FFMPEG (avcodec-55.dll) as against the avcodec-57.dll I was using earlier, the code worked perfectly without any error and the resultant h264 file played with ffplay.Here is a full log of the output with GST_DEBUG=GST_CAPS:6.After starting this question Extracting the h264 part of a video file (demuxing) I was actually able to figure out that, Source = ("filesrc", "file-source")ĭemux = ("qtdemux", "demux")ĭnnect("pad-added", demux_pad_added, h264parser)įull Python source: deepstream_test_2.txt (10.9 KB) Qtdemux_src_pad.link(h264parser.get_static_pad("sink")) Here are the modified code snippets: def demux_pad_added(qtdemux, qtdemux_src_pad, h264parser):Ĭaps = qtdemux_src_pad.get_current_caps() Hardcode subtitles using XviD4PSP - Open MP4/AVI File The format of the video file should be detected and default settings should be properly selected in the Format: panel.

When I run the sample unaltered with sample_720p.h264 as source, it works, so the issue is most likely with the way I am adding qtdemux or dynamically linking the Gstreamer pipeline. We have added to GPAC some sample applications demonstrating how to use GPAC to demux MP4 files. The problem is the pipeline fails to start with an internal data stream error because qtdemux cannot be linked to h264parser. To support MP4, I modified the sample app to add a qtdemux element, and dynamically linked it to the h264 parser element based on the deepstream_test_3 app. Encryption: MP4Box -crypt info.xml -out fileav1encrypted.mp4 fileav1.mp4. Example of such XML files can be found in our test base. Eventually, I want to use an RTSP camera source. To use MP4Box for encryption or decryption, use the following command lines where the file ‘info.xml’ is an XML file that provides encryption parameters, as described in more details here. I am trying to modify the deepstream_test_1.py app included with the DeepStream Python bindings to take an MP4 file as input (sample_1080p_h264.mp4) instead of an H.264 elementary stream (sample_720p.h264).
