#6625: "Freezes" transcoding RTP g.711 stream to mp3 -------------------------------------+------------------------------------- Reporter: sagonzal | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: rtp g.711 | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Hi, I am trying to connect to a live RTP stream of g.711 audio from an intercom and then output it as an mp3 file. '''FFmpeg version''' N-86996-g931c0ac95c-Reino cross-compiled for Windows 64 w/ pthreads and debug=3 enabled '''command:''' ffmpeg -re -f mulaw -i rtp://10.200.1.14:32760 -sample_rate 44100 -filter:a "asetrate=9000" -acodec libmp3lame -ar 44100 live- rtp-g711-toMP3.mp3 -report '''output:''' “live-rtp-g711-toMP3.mp3” '''report:''' “live-rtp-g711-toMP3-REPORT.log” '''gdb backtrace:''' “live-rtp-g711-toMP3-BACKTRACE.txt” With this command, the window “freezes” after printing “''[udp @ 0000002c748241e0] end receive buffer size reported is 65536''”. The command line will stay that way indefinitely until I enter ''ctrl+c'' (''q'' doesn’t work), after which it seems to say that nothing was written to the output, and the output file produced is indeed empty/unplayable. Unfortunately I cannot provide access to th live rtp stream, as it requires VPN access. I saw something about using ffplay if my output isn’t reproducable, but I’m not sure how to do that. If it’s needed could you please give more details on how to do this? However I can say that, using Wireshark, I have confirmed that there is traffic coming through port 32760 — packets using the RTP protocol and g.711U payload type, as expected (''attached screenshot “wireshark- RTP-g711-traffic.png”''). I Analyzed and Saved the data from Wireshark as a "synchronized forward stream audio” in the .raw format, then used the same command with the .raw input instead of an RTP stream, and that works: '''command:''' ffmpeg -re -f mulaw -i wireshark-rtp-g711-syncedRAW.raw -sample_rate 44100 -filter:a "asetrate=9000" -acodec libmp3lame -ar 44100 wireshark-rtp-g711 -syncedRAW-toMP3.mp3 -report '''input:''' “wireshark-rtp-g711-syncedRAW.raw” '''output:''' “wireshark-rtp-g711-syncedRAW-toMP3.mp3” '''report:''' “wireshark-rtp-g711-syncedRAW-toMP3-REPORT.log” I don’t know why the command works with the saved audio from Wireshark but not with a live stream. I’m very new to FFmpeg so I apologize if this is just a user error. I would appreciate any light that can shed on this problem! Thanks very much, Sara -- Ticket URL: <https://trac.ffmpeg.org/ticket/6625> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#6630(undetermined:new): Using stream segmenter produces .ts file with non-zero start time

#6630: Using stream segmenter produces .ts file with non-zero start time -------------------------------------+------------------------------------- Reporter: | Type: defect casey.bateman | Priority: normal Status: new | Version: Component: | unspecified undetermined | Blocked By: Keywords: | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- I am trying to adjust the timestamps of a collection of mpegts files. The timestamps of these files seem to be all offset by some arbitrary number 1.466667s - 1.485333s. The HLS stream that I am generating contains 3 separate qualities. A 1280x720, and 852x480 version. Each of the segments for these qualities come in individually with identical timestamps. I rewrite the timestamps by running them through the stream segmenter and specifying `-initial_offset`. I do this because the timestamps are not always continuous between segments as I receive them. pre stream segmenter 1280x720 segment ffprobe output {{{ ffprobe version N-85091-g23ae3cc Copyright (c)

#6607(ffplay:new): ffplay has difficulty decoding 4.0 PCM

#6607: ffplay has difficulty decoding 4.0 PCM -----------------------------------+--------------------------------------- Reporter: kieranjol | Type: defect Status: new | Priority: normal Component: ffplay | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -----------------------------------+--------------------------------------- Summary of the bug: ffplay and VLC have issues playing 4.0 PCM audio, whether in WAV, MOV or MKV containers. When making `sine` waves with `lavfi`, ffplay produces silence for 4.0, though 2, 5, 6 channel audio is played back OK. VLC produces throbbing, distoreted audio but that's outside of the scope of this issue I guess. How to reproduce: Generate a sine wave with ffmpeg and then play it back with ffplay. {{{ ./ffmpeg -f lavfi -i "sine=frequency=1000:duration=5:sample_rate=48000" -ac 4 -c:a pcm_s24le test.wav ffmpeg version N-87034-geca2a49 Copyright (c) 2000-2017 the FFmpeg developers built with Apple LLVM version 7.3.0 (clang-703.0.31) configuration: libavutil 55. 74.100 / 55. 74.100 libavcodec 57.103.100 / 57.103.100 libavformat 57. 76.100 / 57. 76.100 libavdevice 57. 7.101 / 57. 7.101 libavfilter 6.100.100 / 6.100.100 libswscale 4. 7.102 / 4. 7.102 libswresample 2. 8.100 / 2. 8.100 Input #0, lavfi, from 'sine=frequency=1000:duration=5:sample_rate=48000': Duration: N/A, start: 0.000000, bitrate: 768 kb/s Stream #0:0: Audio: pcm_s16le, 48000 Hz, mono, s16, 768 kb/s File 'test.wav' already exists.

#6292(undetermined:new): overlay filter's shortest=1 doesn't take effect.

#6292: overlay filter's shortest=1 doesn't take effect. -------------------------------------+------------------------------------- Reporter: Gyan | Type: defect Status: new | Priority: normal Component: | Version: git- undetermined | master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Setting **shortest=1** in the **overlay** filter doesn't work. If the main input is longer, the overlay runs till the end of that video. If the secondary input is longer, whether it's a video or a looped single image, encoding proceeds till the EOF of the main input but FFmpeg doesn't exit. Doing a soft exit works and the output file is valid (tested with MP4 output). However, this is not a practical option when processing videos in bulk. Can't use output option **-shortest** as workaround if there are no other streams being muxed (or they are shorter). Tested with multiple MP4/MOV inputs as main video. Tested with multiple images and couple of MP4/MOVs as secondary input.
